Google recently released guetzli, a JPEG encoder that claims 20%-30% smaller compressed images, while still retaining the same image quality. I thought this looked pretty cool, so I gave it a try. It seems to work quite well. I was able to compress a 2.7MB image down to 1MB. The only downside was that guetzli took almost 20 minutes to compress the image. I hope Google improves the speed of the tool, but it’s worth a shot if you have some images that need compressing.
